Definitions
- the present invention relates to an automatic programming method for effectively and accurately creating NC data for combined machining.
- NC data NC program
- a conventional programming apparatus is a single purpose device having a function of creating NC data for particular machining alone, plural kinds of programming apparatuses are employed for creating NC data for combined machining.
- NC data for combined machining for carrying out turning and milling together part programs respectively relating to turning and milling are created beforehand. Then, NC data for turning is created based on the part program for turning by the use of a programming apparatus, whereas NC data for milling is created based on the part program for milling by means of another programming apparatus. Further, NC data for turning and milling are so edited as to create NC data for the combined machining.
- the object of the present invention is to provide an automatic programming method for creating NC data for combined machining effectively and accurately.
- the present invention comprises the steps of: (a) creating a part program for combined machining which includes first and second part programs respectively relating to first and second kinds of machining; (b) providing a group of translating means which includes first and second translating means for translating the first and second part programs into first and second NC data respectively relating to the first and second kinds of machining; (c) reading the part program for combined machining one block by one block, and automatically determining a kind of the part program of the block thus read; and (d) automatically translating the part program of the read block in said step (c) by use of that translating means whose kind corresponds to the result of determination in said step (c), whereby NC data for combined machining is automatically and continuously created on the basis of the part program for combined machining.
- a part program for combined machining including the first and second part programs respectively relating to the first and second kinds of machining, is read one block by one block, a kind of the read part program is automatically determined, and automatic translation to NC data is effected by the use of that translating means whose kind corresponds to the kind of the read part program, among the group of translating means including the first and second translating means for translating the first and second part programs into first and second NC data respectively relating to the first and second kinds of machining.
- NC data for the combined machining can be automatically and continuously created on the basis of the part program for the combined machining. Accordingly, it is unnecessary to create various part programs, which cooperate to form the part program for the combined machining, separately for kinds of these part programs.
- a method of an embodiment of the present invention is intended to create an NC data for a combined machining which is a combination of turning and milling.
- an automatic programming apparatus for embodying this method comprises a processor (CPU) 1, a read-only memory (ROM) 2, a random-access memory (RAM) 3, an NC data storage memory 4, a keyboard 5, a disk controller 6, and a graphic display unit (CRT) 7. These elements 2 to 7 are connected to the CPU 1 via buses 8.
- a part program for combined machining which is inputted to the unit of Fig. 1 for creation of an NC data for combined machining, includes first to third programs for turning, milling, and general purpose machining which are respectively created by an operator with the use of first to third automatic programming languages (FAPT TURN, FAPT MILL, FAPT) for turning, milling, and general purpose machining.
- the first to the third part programs are arranged in the part program for combined machining in order of machining sequence in the combined machining.
- the part program for combined machining is stored in the floppy disk FL.
- floppy disk FL for use as a system disk are various system programs and first to third interpreters (interpretive programs) which respectively serve as translating means for translating the first to third part programs for turning, milling and general purpose machining into first to third NC data for turning, milling and general purpose machining, respectively.
- the part program for combined machining, etc. are transferred to and stored in the RAM 3 from the floppy disk FL under the control of the CPU 1, an NC data creating process shown in Fig. 2 is executed by the CPU 1.
- the CPU 1 reads the initial block of the part program for combined machining stored in the RAM 3 (step S1), and determines whether or not the part program sentence in the initial block is written in the first automatic programming language for turning, to thereby determine whether or not the initial block relates to a part program for turning (step S2). If the determination result is affirmative, the CPU 1 translates the program of the initial block into a first NC data for turning by means of the first interpreter (step S4). More specifically, creation of NC data for turning, identification of a tool for turning, etc. are executed in accordance with numerical data, a tool management number, etc. respectively described in the part program of the initial block. Then, the execution results are stored in the memory 4.
- step S2 determines whether or not the program sentence of the initial block is written in the second automatic programming language for milling, to thereby determine whether or not the initial block relates to a part program for milling (step S3). If the determination result is affirmative, the CPU translates the program of the initial block into a second NC data for milling by means of the second interpreter (step S5). More specifically, creation of NC data for milling, identification of a tool for milling, etc. are executed in accordance with numerical data, a tool management number, etc. respectively described in the program of the initial block, and then the execution results are stored in the memory 4.
- step S2 When both of the determination results in steps S2 and S3 are negative, and therefore, it is determined that the program sentence of the initial block is written in the third programming language for general purpose machining other than the first and second programming languages for turning and milling, the CPU 1 translates the part program by means of the third interpreter, and executes processes associated with commands written in this part program. Then, the CPU causes the execution results to be stored in the memory 4 (step S6). Next, a determination is made as to whether or not the initial block indicates program end (step S7).
- the determination result in step S7 is negative, and hence the CPU 1 reads the second block of the part program for combined machining (step S1), and further sequentially executes corresponding ones of steps S2 to S7 with respect to the second block.
- part program sentences for turning, milling and general purpose machining are written in different programming languages, however, the part program sentences for turning, milling and general purpose machining may be written in a programming language of the same kind.
- each of processes respectively associated with turning and milling is defined in the part program for combined machining by a specialized command, the content of a command described in a respective part program sentence is distinguished to thereby determine the kind of this part program sentence, and further a determination is made as to whether or not the program sentence indicates the program end each time the creating process of NC data for turning, milling or general purpose machining with respect to the respective program sentence is completed.

Abstract
Procédé de programmation automatique permettant de préparer de manière correcte et efficiente des données de commande numérique pour un usinage complexe. Un programme de pièces pour usinage complexe stocké dans une mémoire à accès sélectif (3) est chargé (S1) bloc par bloc dans le processeur (1) d'un appareil de programmation automatique. Les instructions de programme de chaque bloc sont écrites dans l'un de trois langages de programmation automatique pour tournage, fraisage et à usage général. Le processeur détermine (S2, S3) quel langage est utilisé dans l'instruction du bloc de sortie, et traduit l'instruction de programme en utilisant un premier, un deuxième ou un troisième interpréteur, en fonction du résultat du test. Les résultats sont placés (S1-S6) dans une mémoire (4) sous forme de données de commande numérique. Ce procédé permet de préparer automatiquement et en continu un programme de pièces pour usinage complexe.
